IMPROVEMENTI'NV WATER AND GAS CUT-OFFS.

Specification forming part of Letters Patent No. 147,949, dated February 24, 1874 application led February 11, 1874.

To all whom it may concern:

j Be it known that I, HENRY KOETHE, of Baltimore, in the county of Baltimore and State of Maryland, have invented certain new and useful Improvements in Vater and Gas Cut-Off, of which the following is a specification:

This invention relates to certain improvements in cocks or cut-offs for water and gas, provided with means for permitting the escape of the waste-water or condensed matters from gas accumulating in the valve-chamber; and it consists in the employment of an apertured valve-stem, which operates through a stuffing-box located in proper respect to the valve and drip chambers of the cock, so as to form a tight joint between the valve-stem and the valve-chamber, and also guide the former in its movement.

In the accompanying drawings, Figure l is a vertical section of a cock or cut-oft', showing the valve closed and the waste-passages in the valve-stem in communication witha Waste or outlet chamber. Fig. 2 is a similar view, representing the valve in an open position to permit the iiow of water or gas.

The letter A designatesA the cock or cut-off casing, which is divided into two chambers, a I), by a plate or diaphragm, B, said chambers being connected, respectively, by screwthreaded sockets c (Z with the inlet and service sections or branches of water or gas pipes. A cap-tube, C, screwed into the valvechamber, contains a stem or rod, VD, which passes through the upper end of said tube, and carries also a disk-valve, E. rlhe valve is borne down or forced upon its seat in the' plate B by means of a spiral spring, F, which encircles the valve-stem, and the valve may be made separate from the stem, and be secured to the same by a screw-thread, c, as shown. This screw-thread will also permit the valve to be adjusted to compensate for wear, 85e. The stem is extended below the valve, and is made long enough to pass nearly through a waste or outlet chamber, G, applied to the base of the valve-chamber. The

lower portion of the valvestem is provided with an axial bore or vertical passage, H, and with two or more horizontal openings, I, communicating with said passage, and located at the top and bottom thereof, and, if desirable, also in the center, as shown in the drawing. The waste or outlet chamber is applied to a tubular extension or socket, K, of the valvechamber in a detachable manner, and said socket is designed to receive an internal packing-gasket and stuffing-box, L, through which the valve-stem passes, as shown. Said stuffing-box subserves the double function of producing a tight joint between the valve and waste or outlet tube, and also to guide the valve-stem in its movement.

Vhen the valve is elevated or removed from its seat, as represented in Fig. 2, the uninterrupted flow of water or gas takes place through the valve-chamber; but as soon as the retaining device which has held the valve-stem in a raised position is released, the valve will be closed or forced down upon its seat by the action of the spring combined therewith, as shown in Fig.

The waste-water accumulating or retained in the valve-chamber, upon the closing of the valve, is carried oif to prevent freezing, 85e., by means of the passage and openings in the valve-stem, the upper horizontal opening being in communication with the valve-v chamber, and the lower opening permitting the wastewater to escape into the outlet-chamber.

When the cock or cut-ofi' is used in connection with gas-pipes, the open waste or outlet tube is superseded by a cap-tube to prevent the escape of gas, the passages in the valvestem being, in this instance, employed for re moving from the valve-chambers condensed substances, and other impurities collecting in the same.

A cock or cut-off constructed according to my invention is simple in construction and effective in use, and, by reason of having the extended valve-stem apertured and arranged in respect :to a waste-chamber as shown, there is no liability of clogging, the stem moving freely up and down through its stuffing-box at all times.

The valve is designed to be operated by a cord orrod connected with its stem, and extending into a room remote from the place where the cock or cut-off is located, and said operating-oord is combined with a suitable valve-stem, waste or outlet tube, and the va1vcratohet and pawl or other retaining devioe, for. chamber, substantially as described. v holding the valve in an open or elevated posi- In testimony that I claim the foregoing I tion7 and so constructed that the position of have hereunto set my hand this 9th day of the valve may be regulated for permitting a February, 1874. greater or less flow of Water or gas.

Having thus described my invention, what I claim as new, and desire to secure by Letters Witnesses: Patent, is- JAivrns L. NoRRIs,
